Hi I have the older, classic version of RG35XX with GarlicOS. Everything works fine but I'm curious to check other os - garlic for RG35XX looks more or less dead in terms of further development to me, and other os are still developed.

What tempts me the most are apparent additional consoles available in other OS. I'm just not sure if it's worth it.

NDS emulation is covered quite widely here and in other places, as I understand these few games where stylus and microphone are not needed/rarely used are playable and can be enjoyed. But what about other consoles?

N64 is also discussed, but how many games are really playable? Dreamcast I doubt is playable, but what about things like Saturn? Is 3DO or Jaguar playable (In Garlic they are too slow to enjoy). Are there any other devices these os can emulate and garlic cannot?
